Correct return code of e4k_reg_write().

Browse Source 
In contradiction with the documentation, e4k_reg_write() was
returning the value 2 upon success (the number of bytes written),
not zero as documented.
Patched to return zero upon success.

As a consequence, this corrects also the return value of
e4k_reg_set_mask() and e4k_dc_offset_calibrate().
